You may work on the problem set individually or with up to $3$ of your classmates. If you choose to work with a group, you all need to be attempting the problems and discussing them together or you will miss out on learning the concepts, which is the entire point of doing these problem sets. Each student needs to submit their own work on Gradescope. To submit, click the "Gradescope $1\mathrm{.}3"$ link on Canvas or click the assignment link in Canvas.

Your work should be submitted as a single PDF with each problem on a separate page.

Your car needs gas before you can go to work this morning. You decide to go to the gas station that is out of the way, but where gas is $$\frac{0\mathrm{.}10}{?}$ gallon cheaper than the gas station on the way to work. This gets you into work $6$ minutes later than going to the other gas station. If your wage is $$\frac{20}{?}$ hour and you have to purchase $15$ gallons of gas, was this worth it$?$ Why or why not?
